Some companies, such as Google, use code covered by GPL to offer their services through the Web. Do you plan to extend GPL 3 copyleft to request code publication in this case too, considering this behavior like a product distribution?

Running a program in a public server is not distribution; it is public use. We’re looking at an approach where programs used in this way will have to include a command for the user to download the source for the version that is running.

But this will not apply to all GPL-covered programs, only to programs that already contain such a command. Thus, this change would have no effect on existing software, but developers could activate it in the future.

This is only a tentative plan, because we have not finished studying the matter to be sure it will work.
